The calculator can work with just the AAA batteries. But, without the backup battery, you'll lose all the contents of memory when the AAAs die. The backup battery is intended to keep the contents refreshed while you replace the AAAs.

Wont turn on


Good morning, afternoon, evening or night; whatever time of day you are viewing this solution post. Thank you for choosing FixYa to assist you. You are having problems because you calculator won't turn on. I think you should try changing the batteries. Did you know that your calculator has two batteries powering it? Not only are the 4 AAA batteries powering it, but there is also a CR 3V Lithium Back Up battery powering it as well. First, try changing the 4 AAA batteries. If that still does not power your calculator properly, you will need to replace the lithium back up battery. You can find this at a department store or store that carries electronics. To do this, open your regular battery compartment. Above the AAA batteries is a compartment that says "BACK UP BATTERY CR1616 OR CR1620" with a picture of it. Use a small crosshead screwdriver to open the compartment. Take the old battery out and replace it with the new one. Rescrew the lithium battery compartment back on and close the AAA battery compartment. Turn on your calculator and see if that works. I hope this solution solves this.

TI 82 Does it need the disk battery and 4 AAA batteries to work?


No. The calculator runs on the four AAA batteries. The lithium battery is solely to retain the contents of the memory while you change the AAA batteries. If you don't care about retaining the memory, you don't need the lithium battery. You do, however, need the AAA batteries to use the calculator.

Hi imagenius1,

You need to free up some memory. Try clearing your RAM memory. Your calculator should operate properly afterward.

Press [2nd] [MEM] [7] [1] [2]

If the steps above did not reset the memory to your Ti 83 family calculator try the procedures below.

Please be prepared to re-install the calculator's OS if you run through this process.

If you have a straight Ti 83 without the Plus or, Silver Edition label goto (Procedure 2) below. If your Ti calculator is a Ti 83 Plus or better goto (Procedure 1).


(Procedure 1).

The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.



  2. Steps to re-installing the operating system:
    ~Connect the TI Connectivity cable between the PC and the calculator.
    ~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
    ~Follow the on-screen directions to reinstall the calculator's OS. If you could not install the new OS on your calculator goto step 4.


  3. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.

  4. If the above process did not reset your calculator. Try re-doing (Procedure 1) and, extend the time in step 4, by 5 minutes to 10 minutes before you put all the batteries back in the calculator.

(Procedure 2).


For a straight Ti 83 without the Plus or, Silver Edition label try the procedure below.

My TI 83 Plus won't turn on, I adjusted the brightness, held DEL while reinserting batteries, replaced batteries but nothing changed


hi bckyshldn,

Did you remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. In the procedure that I give, you hold [DEL] and, re-insert 1 battery. I'm going to go ahead and, restate my instructions for a ti 83 Plus that won't turn on.

Make sure the batteries are in correctly? The batteries alternate negative/positive, positive/ negative and so on. The first time I put the batteries in, I didn't have them in correctly. I know if it happen to me anybody could make the same mistake. and of course the calculator will never come on if the batteries aren't in correctly.

The process below should reset your calculator.

Please be prepared to re-install the calculator's OS if you run through this process.

Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.


  1. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR],
    reinsert the AAA battery and then turn the calculator on. The calculator should display the
    message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message. If calculator did not display the message try pressing and releasing the [2nd] key followed by pressing and releasing the up arrow for one second. goto step 2.
  2. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display
    "Waiting...Please install calculator software now". Follow the instructions for the
    TI-83 family or TI-84 Plus family to reinstall the calculator operating system. If the calculator did not turn on connect the calculator to the computer and open Ti Connect. Next, open Device Explorer. Is the calculator asking to be installed? goto step 3.
  3. Steps to re-installing the operating system:

    ~Connect the TI Connectivity cable between the PC and the calculator.
    ~Click on Start >> Programs >> TI Tools >> TI Connect >> TI OSDownloader
    ~Follow the on-screen directions to reinstall the calculator's OS. When or, if the calculator install the fresh OS goto step 4.


  4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.


If the above process did not work. Try re-doing the procedure and, extend the time in step 4 by 5 minutes to 10 minutes before you put all the batteries back in the calculator.


Now just in case this calculator wasn't posted correctly. Here's my instructions for a Ti 83 that won't turn on. This is not the same procedure that the Ti 83 Plus has.

  1. Try a new set of AAA batteries.
  2. Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds. Now, Pressing the [2nd] key followed by pressing and releasing the up arrow; repeat as necessary. Is the screen showing any activity? If not continue the process.
  3. Remove one of the AAA batteries. Press and hold the [ON] key for 20 seconds. Reinsert the
    AAA battery and then turn the calculator on.
  4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary. And of course if the calculator does not turn on, I re-do the procedure and, increase the amount of time by 5 minutes to ten minutes that all the batteries are removed.

I have a TI-83 Plus. It just died. I have replaced the 4 AAA batteries and the lithium 1616 backup battery. I have checked to verify that the screen hasn't just dimmed. I get nothing. Any ideas?


Remove all four AAA batteries. Press and hold the ON key for ten seconds. Replace the batteries. Turn the calculator on (you may have to adjust the screen contrast again).

If this doesn't do it, please add a comment to this post and we'll go on from there.

I put new lithium triple aaa batteries in my TI-83. Nothing happened . days later it turned on worked for a little while then stopped. would it help to change the round lithium battery? Do you know what...


The button cell backup battery keeps the memory electrically refreshed when the calculator is turned OFF. The necessary power for regular use is supplied by the 4 AAA batteries (main power). That nothing happened when you put in a fresh set of (expensive) lithium batteries may be due to the screen being too dim to see anything.

If the calculator displays RAM CLEARED each time it is turned on, it may be due to a depleted backup battery. The battery model number is CR1616 or CR1620. On my TI84PLUS the backup battery is of type 303 (Sony) or SR44SW (Maxell).
